A new Smalltimes article details the progress made on smart dust over the last few months. robots.net covered smart dust and micro rocket technology and related privacy concerns in early May but a lot has changed since then. Kris Pister's micro-sized sensor platforms are moving into a commercial phase. A company called Crossbow is selling a prototype kit with 3 smart dust "motes" for $950 that should be quite interesting for all sorts of robotics uses. The Crossbow prototype motes are a whopping 1 inch in size but Pister's goal is for production units 1mm or smaller.
